Armed To The Teeth: There's no weak link in the Armor series from GTR Lighting. We love the incredible style these LED bulbs add when they're on and when they're off. Take a look at that killer black-chrome styling and the unique outer shell design.

Internally: To brighten the night, the Armor series uses 2835 SMD LED chips that are the bleeding edge of LED tech right now. Built to provide 165 degrees of bright light, they're good enough to do any job you need. They're bright enough, at 750 lumens to even serve as functional fog lights.

No Flickering: Baked into the Armor series you have a constant current driver to ensure that no vehicle voltage issues cause flicker or premature burnout. While we've seen other bulbs that cost less, they don't have this feature so instead of buying those over and over, buy the Armor series and do it right the first time.
